Claim rather difficult. OGH line 9 Ob 50/16t supports the skier's self-responsibility.
The OGH in 9 Ob 50/16t clarified: a wind fence visible from afar and well recognisable is not an atypical hazard. Anyone colliding with it has a difficult starting position. The slope safety duty is not an obligation to protect the skier from every possible hazard.
Your own accident insurance is the economically relevant first port of call. A brief initial legal assessment can make sense, because the details often reveal anchors that are not obvious at first glance (such as recognisable material defects, maintenance documentation).
